I have Game A. Some nonzero number of people have purchased it or gotten it through bundles.
I have created Game B. It's an add-on to Game A. I would like to give Game B to all the people who have previously purchased Game A, but NOT to anyone who buys it from now on. (Game B will be put up for sale separately)
How do I do this?
You could create a 100% off sale (that has claiming enabled) with a “ownership requirement” sale condition: https://itch.io/docs/creators/sales#sale-conditions
While the sale is active, though, anyone who obtains game A will be able to access the sale.
To limit who has access to the sale, you can enable a coupon code. Then you can send out an email using out email tool to just the current owners of the game with a link to that sale’s coupon code URL.
